Prepping for your Receptiva test (what to expect, do & not do)
If you haven’t had one before (or even if you have), getting ready for a biopsy can come with a lot of questions.
From the thorny topic of sex after endometrial biopsy to pain relief and flying post-test, they’re all super-valid, so we’ve rounded up some of the most-asked, specific to the MyReceptiva™ test – the only test that can reliably detect inflammation associated with endometriosis.
Heads up: TRB readers can save $85 on their MyReceptiva™ test kit.
How is the Receptiva test done?
Thinking about – or prepping for – your Receptiva™ test? First things first: this is a simple, routine procedure, done all the time in OB/GYN offices. In fact, it’s often compared to having your blood drawn, with the key difference being that it’s a pelvic exam.
That said, for many people it can bring up nerves or anxiety, and that’s completely normal. We’re here to give you a deep dive into what to expect, what to do (and not do), and help ease any concerns so you feel informed and supported.
What to expect
A thin, flexible catheter (about the width of a spaghetti noodle) is gently inserted through the vaginal canal and cervix, into your uterus. It’s placed against the uterine lining and a suction technique is used to collect a small sample of cells.
The whole process is quick (most biopsies are done in under five minutes) and you may feel some brief discomfort or cramping. This usually settles within 10-15 minutes, after which you can go about your day as normal.
The tissue sample is then sent overnight to the lab, where it’s tested for a protein called BCL6. This marker should not be present during the mid-luteal phase of your cycle, and its presence indicates inflammatory conditions most often associated with endometriosis, which can affect fertility.
When in my cycle should I take the Receptiva test?
Timing is everything. The MyReceptiva™ test needs to be taken 7-10 days after ovulation. This is the luteal phase, and ensures the most accurate result when screening for BCL6.
To help you pinpoint the best time, your MyReceptiva™ kit includes a simple ovulation predictor. If you’re not ovulating regularly, your healthcare provider may work with you to track or support ovulation ahead of the test.
If you’re using hormonal birth control, it’s important to discontinue it in advance, as ovulation must occur naturally for the timing to be accurate. This can take up to 8 weeks after going off BC.
If you’re worried about stopping birth control because of pain or pregnancy concerns, you’re not alone. What makes the MyReceptiva test valuable is that it pinpoints the window in your cycle when endometriosis is naturally driven by estrogen, causing inflammation. It’s also the only test that looks directly at the site where endometriosis begins.
Once you’ve had your test and received results, you can go right back on birth control if you choose — and if the result is positive, you’ll have the clarity you need to start planning long-term management.
Is the Receptiva test painful?
Most patients describe it as uncomfortable, rather than painful – often compared to a brief cramp, pinch, or pressure similar to a Pap smear or IUD insertion.
If you’re concerned about discomfort, you can absolutely:
- Request a mild sedative or local anaesthetic
- Take an over-the-counter pain reliever like ibuprofen 30-60 minutes before your appointment
- Ask your provider to talk you through the procedure step-by-step
Discomfort generally resolves quickly, and recovery time is short.
Are there any side effects?
Most people experience light cramping or spotting for a few hours after the test. These symptoms are normal and can be managed with rest, hydration, and gentle care.
Serious side effects (such as heavy bleeding or infection) are very rare, but you should contact your provider if you experience:
- Persistent or heavy bleeding
- Fever or chills
- Severe pain that doesn’t improve after a few hours
Mental & emotional prep
Pelvic exams and biopsies can feel deeply vulnerable. If you’re navigating anxiety, past trauma, or heightened stress, it’s important to communicate your needs ahead of time.
You don’t have to disclose trauma specifics. A simple, “I’m feeling pretty anxious – I’d like this to be as gentle and supported as possible” is enough.
Here are some tips that might help:
- Bring a support person – even if they wait outside
- Request a calm, unrushed appointment
- Use grounding techniques, like breathwork or guided visualisation
- Book time off afterward to rest, or do something soothing
You deserve to feel safe, seen, and supported throughout this process. If your provider doesn’t offer that? You have every right to find someone who does.
Can I have sex before the Receptiva™ Test?
Having sex won’t impact your test result. That said, there are two things to keep in mind:
- Timing: The test needs to be done 7-10 days after ovulation. If you’re on birth control or suppressing ovulation, you’ll need to pause it and allow a natural cycle first. If you’re avoiding pregnancy, this is something to bear in mind.
- Comfort: Many people choose to avoid penetrative sex the day before, simply to reduce any potential tenderness or irritation. Doctors generally recommend avoiding sex for 48 hours before an endometrial biopsy, and for a few days afterward, to reduce the risk of infection and support proper healing.
Can I have sex after endometrial biopsy?
This is a common concern – and we get it! The general recommendation is to wait 24-48 hours before resuming vaginal sex, but listen to your body. If you’re still cramping, spotting, or feeling sensitive, hold off a bit longer.
Top tip: Opt for gentle intimacy and open communication with your partner once you’re ready.
Can I fly after the biopsy?
Yes, you can fly after your MyReceptiva™ test – many people do! Just prepare ahead:
- Wear loose, comfy clothing
- Stay hydrated
- Take it easy (think: no heavy lifting or rushing through terminals)
If you’re prone to discomfort or anxiety while flying, consider scheduling a flight for later the same day or the day after, and give yourself permission to rest.
What if I start my period?
You’ll need to wait until 7-10 days after ovulation for the biopsy, so if you’re on your period, it’s not time yet. Your provider will likely schedule your test for days 21-23 of a standard 28-day cycle.
What makes the Receptiva test different?
Unlike standard pathology reports, the MyReceptiva™ test goes beyond basic tissue analysis. It specifically detects the BCL6 marker, which research has shown is linked to inflammation associated with endometriosis – even in those with no symptoms.
This can be a game-changer for anyone with suspected endometriosis but no visible signs on laparoscopy or scans, as well as people with unexplained infertility, or those experiencing failed IVF cycles.
